Why don't ISPs peer with everyone?

I'll answer with some questions:

Where should they peer?

Who should/will pay for the routers and aggregation ports?  How about 
the power, racks, and building space?

Who should/will pay for the network engineers to do the configuration 
for the peering?

In short, peering isn't free for anyone.  It _can_ be efficient in some 
cases but in others its damn pita and you never really know which one a 
given case will turn into.  (its not always a problem of technical 
competence)
